NFC tag IC with increased RF performance supports 48 up to 888 bytes of memory

November 05, 2012 // By Julien Happich
NXP Semiconductors has released the NTAG21x family of NFC tag IC products, the company's 2nd generation of devices with a choice of memory sizes from 48 up to 888 bytes and a number of new features such as an UID ASCII mirror, a NFC counter, an integrated originality signature and password protection.

For the first time, these features address customer demand for multi-application support, fast serialization, smaller footprints and simple product authentication capabilities, claims the manufacturer.

The NTAG21x family is comprised of four different products, defined around specific application categories. NTAG210, NTAG213, NTAG215 and NTAG216 will offer respectively 48, 144, 504 and 888 bytes of user memory, corresponding to the maximum message size that can be stored. 32-bit password authentication offers a simple protection mechanism for data stored into the tag. The UID ASCII mirror automatically maps the IC unique serial number to a stored NDEF message, thus greatly simplifying tag serialization e.g. in smart poster applications.

With its 24-bit NFC counter and NFC counter ASCII mirror, the IC measures the number of interactions occurred between NFC devices and the tag, and appends it to a stored NDEF message, useful to improve usage analytics in smart advertisement or location based services. The integrated originality signature enables the detection of unauthorized NTAG copies, thus providing a simple but powerful product authentication method. A new Fast Read command speeds up tag registration in inline processes such as print media or product label manufacturing. A special variant of the NTAG216, called NTAG216F additionally offers a configurable Field Detection pin and a Sleep mode, features particularly required in electronics pairing applications.

All products are fully NFC Forum Type 2 Tag compliant, and share the same optimized RF sensitivity, making them the performance benchmark in their category. The NTAG21x family is available now in sample quantities through selected NXP partners including SMARTRAC, Identive, and LSIS.
